The entire Internet is built on swapping between fibre and copper. There’s less and less of it now that fibre optics have reduced in complexity and cost so that they can be run into people’s homes but up until probably 10-15 years ago almost the entire world’s Internet travelled the last few miles on copper lines while the core infrastructure was fibre. ISDN, ADSL, VDSL are all built on media-converters in one form or another. So is probably around 75% of all LAN technology today because UTP ethernet is so much cheaper and easier to build than fibre ethernet LANs.
